In a nation where rising numbers of people are dropping out of organized religion, one dynamic religious movement continues to display remarkable strength. The black church.

Religion can be a critical resource in reducing death anxiety, according to a developing body of research.

Research lifting up the experiences of mothers facing hardships, whether in a homeless shelter in the Southwest, or in a maximum-security prison in the Midwest, or ostracized with AIDS in sub-Saharan Africa, suggests many women rely on religion and spirituality for a pathway beyond despair to having a sense of hope for the future.

Forget looking like Kate Moss. A developing body of research suggests faith can provide a safe haven from a secular culture that encourages women to fit into a body type that comes naturally to only about one in 20 females.
